[QUOTE="Bill Johnson, post: 1042761, member: 84129"] The simple answer is that the neck is not sealing prior to being exposed to burning powder. H1000 is hard to ignite so use a good magnum primer like Fed 215 and be sure you have good neck tension, .003 minimum, .005 better and/or possibly even a crimp like the Lee factory crimp. What sometimes happens is that a high energy primer will, by itself, start the bullet moving before good powder ignition. The result is low pressure initially, leading to smoked shoulders. [/QUOTE]
